Howard Wainer, PhD

About

Dr. Howard Wainer is an award-winning American statistician and research scientist. His specialization is the use of graphical methods for data analysis and communication, robust statistical methodology, and the development and application of generalizations of item re­sponse theory. After serving on the faculty of the University of Chicago, a period at the Bureau of Social Science Research during the Carter Administration, and 21 years as Principal Research Scientist in the Research Statistics Group at Educational Testing Service, he is recently retired from his position as Distinguished Research Scientist at the National Board of Medical Examiners. Dr. Wainer has authored hundreds of peer-reviewed journal articles and more than 21 books, including Truth or Truthiness: Distinguishing Fact from Fiction by Learning to Think Like a Data Scientist. He has served on the Scientific Advisory Board since 2016.
